Abstract :
Discrete orthogonal polynomial deconvolution (DOPD) is an accurate and robust method for signal recovery under certain conditions. However, practical applications have been limited by unpredictable instability. The origins of instability, noise effects on the inverse solution, and appropriate selection of the basis set for DOPD are addressed
